Just when I thought to give up on my truck I thought hmm maybe I should take it somewhere, my…read morebrother reminded me of Paul's shop. My truck was in rough shape a shock was bouncing around and rusty crossmembers, old crusty fuel lines. After CMP's magic my truck runs as good as when I first got it, while being swamped with work my truck was done in a timely fashion and Paul communicated everything that might need to be done or what he thinks would be the best option. Very hard to find a reputable shop that does nice work and have a very personable experience if you have a truck that your about to give up on make sure you stop into CMP

The owner, Paul, is a real stand up guy! I personally have zero knowledge when it comes to the…read moreautomotive world & it is very apparent to anyone as soon as I walk into a shop with car issues. A few years ago, something starting rattling under my hood so bad to the point where I couldnt stand the noise anymore and finally went to a local dealership. I was tight on money at the time and my heart sank when I was told that it would cost me $500 to fix... at that point, I was damn near ready to just trash my car completely. Wanting a second opinion, I reached out to Paul. He told me to swing by his shop and let him take a look at it. When I got there, he was in the middle of working on another vehicle but he dropped what he was doing to come over and take a look. He started laughing and shaking his head, took his wrench, tightened a bolt for me and the noise instantly went away. I tried to pay him something for his time but he refused. Most auto shops could care less about you as a person; they just want their money. And if you're someone who is ignorant in that area such as I am, they're going to find a way to get it. Paul could have easily done the same, but he was honest instead and I will forever be grateful for that!!! Never going anywhere else... I highly recommend this place. Support your local businesses and go check out CMP the next time you're experiencing any issues. You wont regret it

The most honest auto repair people you will ever meet. They have fixed our cars both old and new…read morefor almost a decade. When our local KIA dealer told us a required repair would cost over $1,400 we went to Smithsburg Auto for a second opinion. They fixed the car right away for $1,000 less!! Each and every repair is always explained to us in detail and at a much more resonable and affordable price. I will never take my Chevy, Dodge, Kia, or Honda anywhere else these guys are the best!

DO NOT USE THIS AUTO SERVICE. I had the worst auto repair experience on 4/18/26 and will NOT…read morereturn. Adnan Fayyaz and the Zam Zam Auto Sales & Service Team perform partial low quality auto repairs with faulty parts and try to upsell customers to larger more expensive repairs that their autos do not need. They play the old shell game with auto parts to confuse the customers. They are VERY DISHONEST and DISRESPECTFUL, and will take your money without doing the estimated auto repairs that were paid for! Double check their repair work and get your money credits back! I visited Zam Zam Auto on Sat, 4/11/26 for a engine diagnostic and estimate to complete an oil and filter change, replace with new cylinder ignition coil #2, and 6 new spark plugs minor tuneup. The repairs were completed on Mon, 4/13/26 by your mechanics Jef and Israr to repair a check engine light and vsc off blinking light with engine misfire code problem on my 2009 Lexus RX350. I drove my RX350 back to Zam Zam Auto and reported that the same check engine light and vsc off blinking light with engine misfire code problem returned on my 20 min drive to work on Tues, 4/14/26. Jef and Israr requested that I bring my RX350 back on Wed, 4/15/26 to recheck the repairs, since the misfire code was now on cylinder ignition coil #4 and maybe the spark plug was not seated properly. Jef and Israr completed the engine diagnostic again on Wed, 4/15/26 and reported to me that after they switched the cylinder ignition coil from #4 to #2 that now the misfire code had moved back the cylinder #2. They also reported to me that they thought the engine cylinder #2 had low compression and cylinder #4 was fine. Jef and Israr agreed to provide me with an estimate to replace the engine in my 2009 Lexus RX350 with a used engine. The original diagnostic showed a blown cylinder ignition coil #2, the second diagnostic showed a blown cylinder ignition coil #4, and the third diagnostic showed low compression on cylinder #2. I paid for engine diagnostics and repairs that were NOT completed correctly with good parts and left my 2009 Lexus RX350 with the same problem that I came to Zam Zam Auto with on Sat, 4/11/26. I went to a different and reputable Auto Service on Fri, 4/17/26 to complete the new cylinder ignition coil #2 and new spark plug repairs, and demanded and received a refund from Zam Zam Auto to resolve the matter.

Once a year I take my vehicle in for the routine service…read more I make an appointment and reserve a loaner vehicle. The service is quite okay. The folks will great you right away. You get a complimentary wash with service and just bringing it in. I like the video review of the mechanic going over your vehicle and pointing out issues or potential repairs or issues to watch. I was able to pay online. As with many dealership service centers the cost is inflated. I needed a rear window washer blade for $20 (purchased from parts) but was quoted $106 for one. I was quoted a dust filter for $236 and paid $36 (purchased at the dealership parts). They sent other quotes that were declined all totally $4k. Just do a little research prior to going to the dealership. Oh the service drive thru will install wiper blades as a courtesy. I saved $180 just purchasing the parts and installing.

They reviewed the video footage, however do they really think that an employee would be stealing when they know they are being recorded? I would take your car elsewhere.
